SGB/DGB series dry-type, isolating, voltage transformer

SGB (DGB) series three-phase (single-phase) dry-type, isolating, voltage transformer is a multi-coil (double coil and above) structure voltage transformer, the primary and secondary windings are insulated from each other. Its transformation ratios are of fixed and tapping type, which enable voltage bucking and boosting. It can also electrically isolate input and output windings from each other to avoid risks of simultaneous access to electrified body (or electrified metal parts due to insulation damage) and ground hazard. Besides, it also has certain inhibiting effect of various kinds of interference.

Main functions of SGB (DGB) series three-phase (single-phase) dry-type, isolating, voltage transformer:

1. Electrical safety isolation

2. Adjustment of voltage class

3. Overcome center drift, and improve power supplying balance

4. Anti-surge and wave-filtering
